The 1979 film of the 1968 musical Hair was nominated for two Golden Globes, Best Motion Picture, and New Star of the Year (for Treat Williams). The movie ends with a powerful song, “Let the Sunshine In.”

For whatever reason, this tune came to mind after reading some articles over the weekend about how something as simple as higher exposure to sunlight can perhaps kill off the coronavirus.

As all the laboratory science in the world has been marshaled against this virus, and all the money that is being created to avoid a global economic depression, wouldn’t it be amazing if the plateauing of the now familiar COVID-19 growth curve could result from the advent of spring, warm air, and more sunshine?

The first day of spring was officially declared last Thursday, March 19, which happens to be the earliest starting date in the last 124 years. Some commentators have suggested that warmer weather would help weaken the spread of coronavirus, perhaps as early as April, but there is no consensus from scientists and physicians as to whether a change in the weather will have a positive impact on stopping the coronavirus.

What scientists and physicians do know, however, is that increased sunlight and warmer temperatures have been shown to disrupt the transmission of some viruses. Since COVID-19 has only existed for three months, the scientific research is too early to make any credible claims for its reaction to warm weather.

As the sun’s arc across the Northern hemisphere lengthens, the amount of ultraviolet light from the sun will increase rapidly. Ultraviolet light and warmth have been shown to disrupt the transmission of some viruses, but whether it will work with coronavirus is unknown. From a very insightful article (“Spring Equinox: Will season’s longer days, stronger sunlight, warmer air help kill coronavirus?” available at – March 20, 2020), here is part of their conclusion, via quote (and paraphrase):

“Andrew Marshall, a molecular virologist at Loyola University Maryland, said that it’s possible that increased sunlight can destroy the COVID-19 virus. Coronavirus is an ‘enveloped virus’ which are more sensitive to UV rays and warmth, Marshall said. ‘UV rays either mutate or modify the DNA or RNA of these viruses, which leads to instability and death of the virus,’ he said.”

“Viruses that cause influenza and the common cold spread more rapidly among humans in winter thanks in part to dry air, weaker immune systems and more time spent indoors. Anna Yeung-Cheung, a virologist at Manhattanville College, said viruses suffer in warmer weather because the immune system receives a boost with increased vitamin D from sunlight.”

“In the Southern Hemisphere, which just finished summer, coronavirus has not spread nearly as rapidly as it has in the northern part of the globe. How much of that is due to weather is not yet known. ‘The reason why viral infections go down in spring and summer is that your immunity does a lot better in warmer weather,’ she said.”

“People still get sick in warm weather and we’ve seen coronavirus spread in places like Singapore but not nearly as much,’ Yeung-Cheung said. ‘Warm weather has something to do with it. Hopefully, that’s the case with coronavirus here and we see the rates decline.’ ‘It is indeed possible that the [coronavirus] will taper off during the warmer months,’ Marshall said. ‘But as of now, a definitive answer remains elusive.’”

Anecdotal evidence from my own neighborhood shows a marked increase of residents walking, running, and biking outside. I would even say it’s an exponential increase, with many people working out in their garages. According to Dr. Gochfeld, a professor emeritus at Rutgers’ Robert Wood Johnson Medical School, “The potentially good news is that as people spend more time outdoors, there is less transmission than indoors because of dissipation by air currents not present indoors.” Having said this, Dr. Gochfeld was careful to add, “Still, social distancing would be an important factor.”

So, what does all this discussion have to do with investing for income? Well, after watching the bottom fall out of all fixed income markets, with Treasuries being the exception, a bit of sunshine returned to the Investment Grade corporate bond market late last week, even as stocks closed at their lows of the current correction. This was also true for the Investment Grade Preferred Debt market as well, where some rays of sunshine appeared late last week, while junk debt remained a source of funds.

What typically and historically occurs in the earliest days of a market finding a bottom, then establishing a base and emerging from a steep correction, is that investment grade debt that has been hammered by 20%+, starts to rebound – exhibiting the first signs of a shift in sentiment from “doom and gloom” to one of “the world isn’t coming to an end.” This shift needs to build on itself this week – in a meaningful way.

Stocks will follow the trend of the debt markets and if there is new life in the top-tier corporate, mortgage, convertible, and preferred asset classes, then and only then, will a sustainable rally materialize. Hopefully, debt markets will respond favorably to the massive Congressional fiscal stimulus package now brewing.

The S&P closed last week at 2,305, which is below the Christmas 2018 low, representing a market drop of nearly 33%. Not to belittle the damage done, this is an average drop during economic recessions. Since the December 2018 lows were breached, the S&P is prone for an additional 10% to 15% downside, so this week is crucial for the debt markets to pivot higher – so the sun can shine on us yet again.

No matter what the markets bring us this week, it’s nice to know that maybe, just maybe, a big dose of Vitamin D might be the best thing we can all look to for relief from the virus. That implies getting outside as much as possible and keeping a positive mental attitude – which might include some upbeat music.

Consider the following sunshine songs as background music for a better week ahead:

Good Day Sunshine (and Here Comes the Sun) – by The Beatles
Island in The Sun – Weezer
Pocketful of Sunshine – Natasha Bedingfield
Soak Up the Sun – Sheryl Crow
Sunshine Superman – Donovan
Sunshine of Your Love – Cream
Sunshine on My Shoulders – John Denver
Steal My Sunshine – Len
Trip Around the Sun – Kenny Chesney
Walking on Sunshine – Katrina & The Waves
When the Sun Comes Out – Barbra Streisand
You Are the Sunshine of My Life – Stevie Wonder
You Are My Sunshine – Johnny Cash

Past performance is no indication of future results. Investment in securities involves significant risk and has the potential for partial or complete loss of funds invested. It should not be assumed that any securities recommendations made by Navellier. in the future will be profitable or equal the performance of securities made in this report. Dividend payments are not guaranteed. The amount of a dividend payment, if any, can vary over time and issuers may reduce dividends paid on securities in the event of a recession or adverse event affecting a specific industry or issuer.

None of the stock information, data, and company information presented herein constitutes a recommendation by Navellier or a solicitation to buy or sell any securities. Any specific securities identified and described do not represent all of the securities purchased, sold, or recommended for advisory clients. The holdings identified do not represent all of the securities purchased, sold, or recommended for advisory clients and the reader should not assume that investments in the securities identified and discussed were or will be profitable.

Information presented is general information that does not take into account your individual circumstances, financial situation, or needs, nor does it present a personalized recommendation to you. Individual stocks presented may not be suitable for every investor. Investment in securities involves significant risk and has the potential for partial or complete loss of funds invested. Investment in fixed income securities has the potential for the investment return and principal value of an investment to fluctuate so that an investor’s holdings, when redeemed, may be worth less than their original cost.

One cannot invest directly in an index. Index is unmanaged and index performance does not reflect deduction of fees, expenses, or taxes. Presentation of Index data does not reflect a belief by Navellier that any stock index constitutes an investment alternative to any Navellier equity strategy or is necessarily comparable to such strategies. Among the most important differences between the Indices and Navellier strategies are that the Navellier equity strategies may (1) incur material management fees, (2) concentrate its investments in relatively few stocks, industries, or sectors, (3) have significantly greater trading activity and related costs, and (4) be significantly more or less volatile than the Indices.

ETF Risk: We may invest in exchange traded funds (“ETFs”) and some of our investment strategies are generally fully invested in ETFs. Like traditional mutual funds, ETFs charge asset-based fees, but they generally do not charge initial sales charges or redemption fees and investors typically pay only customary brokerage fees to buy and sell ETF shares. The fees and costs charged by ETFs held in client accounts will not be deducted from the compensation the client pays Navellier. ETF prices can fluctuate up or down, and a client account could lose money investing in an ETF if the prices of the securities owned by the ETF go down. ETFs are subject to additional risks:

  • ETF shares may trade above or below their net asset value;
  • An active trading market for an ETF’s shares may not develop or be maintained;
  • The value of an ETF may be more volatile than the underlying portfolio of securities the ETF is designed to track;
  • The cost of owning shares of the ETF may exceed those a client would incur by directly investing in the underlying securities; and
  • Trading of an ETF’s shares may be halted if the listing exchange’s officials deem it appropriate, the shares are delisted from the exchange, or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts stock trading generally.

Grader Disclosures: Investment in equity strategies involves substantial risk and has the potential for partial or complete loss of funds invested. The sample portfolio and any accompanying charts are for informational purposes only and are not to be construed as a solicitation to buy or sell any financial instrument and should not be relied upon as the sole factor in an investment making decision. As a matter of normal and important disclosures to you, as a potential investor, please consider the following: The performance presented is not based on any actual securities trading, portfolio, or accounts, and the reported performance of the A, B, C, D, and F portfolios (collectively the “model portfolios”) should be considered mere “paper” or pro forma performance results based on Navellier’s research.

Investors evaluating any of Navellier & Associates, Inc.’s, (or its affiliates’) Investment Products must not use any information presented here, including the performance figures of the model portfolios, in their evaluation of any Navellier Investment Products.

For these and other reasons, the reported performances of model portfolios do not reflect the performance results of Navellier’s actually funded and traded Investment Products. In most cases, Navellier’s Investment Products have materially lower performance results than the performances of the model portfolios presented.
