I am not buying yet long term Indexes, Fundamentally world in very bad way, USA is matching unemployment levels of 1930's of 25% and will only get worse. Can't go by what is on the shelve at grocery stores, first wave of hoarders knocked out most of common foods, groceries in a few weeks will be back to pretty full shelves. But there are very few industries that are allowed to work in bigger cities. We are very fortunate we don't lack food unlike the dust bowl of the 1930's.
Virus is going to get worse before it gets better, watch the daily number still going up, like watching a chart.
My longer term is looking for 1650 to reverse S&P index futures/hedged and almost always early. Am going long Energies/hedged. Coffee going up nicely, you check out Starbucks drive thru, always busy, but stock is down trend. Am still very much long term long in stocks, but when you hedge when chart patterns show Bearish patterns, smart way to go, plus am older, so rather get little smaller return cause of hedging than like the masses who are SOL. As far as buying more stock, most in down trends, wait for risk takers to get their losses or glory, fine with me. Best to stay with your Trading Plans and learn new, for most, ways to trade.
As far as swing trading and day trading, trend is always your friend, I rather don't make it difficult.
