I mostly day trade CFDs but I’ll chime in for what it’s worth as I usually go long on positions.
Fastly, DataDog, and Proshares Ultra QQQ are my bread and butter. I always buy the dips and sell the peaks on these. Almost every day.
AMD and Cloudflare are another two at the same price point whereby I do the same but not as often.
At a higher price point, I sometimes jump into NVIDIA or MasterCard every now and again and let my positions rise for a week before selling.
Some other frequent appearances where I buy the dip and sell the peak, or buy and let sit for a week or so, are Microsoft, Square, Visa, JP Morgan, Peloton, and Sea Ltd.
On the Invest side, I sold some Shell and BP at a loss recently despite being bullish in the long term for the petro-chemicals and gas industry.
