TAN is a great solar exchange-traded fund. Renewable energy demand is definitely going to grow in 2021. I'm expecting TAN to be weaker in January and stronger in April, simply just because of winter/spring seasons. A nice play on solar's long term uptrend would be to get a TAN calendar spread. Simultaneously, buy a 4/16/21 call$80 = 7.10 ($710) and sell a 1/15/21 call$90 = 1.90 (-$190) for a net entry cost = 5.20 ($520). The 1/15/21C$90 has an open interest of 2,067 with a put/call volume ratio of .51 vs the 4/16/21C$80 has an open interest of 1,085 and a put/call volume ratio of .39, which is very bullish. My ultimate target price for TAN by 4/16/21 is $100 which theoretically equals a 300% profit or an end value of $2000. Do your own due diligence, your risk is 100% your responsibility. Consider being charitable with some of your profit to help humankind. Good luck and happy trading friends...
