Cramer's critique of Wood is accurate. She has no in depth analysis of these companies beyond just pure growth. I owned a lot of the stocks in ARKK seperately even before the pandemic like Roku, Moderna, Cloudflare, Shopify, etc., but I exited them when the story was over. In the end she owns story stocks so in a way similar to any historical bubble, however they are trades not investments.
I remember on PBS there was a documentary about the rise and fall of the Tech Bubble & they interviewed Cramer and he specifically talked about the rise & collapse of ioMega which Cramer said was a phenomenon of growth but that it was just a trade because storage tech is always fleeting.
Cramer is excellent at observing short term trends in markets. That makes sense given his background as a hedge fund manager. He uses the S&P oscillator to determine oversold/overbought sentiment to trade.
Sometimes he is good at long term trends as well. I remember in 2012 he talked about how millennials shop is radically different than their parents and that explains what consumer products do well. That was very accurate. Things like they don't to talk on the phone just texts or twitter; delivery over actually going to the restaurants; streaming over going to the cinema; experiences over buying goods; renting over ownership hence rise in Air BnB, Uber, Rent The Runway, Dollar shave club.
