Quitting your $46K/year job on Oct 21, 2016 to Play Fortnite for a Year instead of investing in PTON (and exercising) would have been a... GREAT IDEA.

If you bought $LLY On Oct 19, 2016 instead of a $72K BMW M2 (inflation adjusted), you might have had $1.3M today (about 13 BMW M2s in 2026).

It's honest about losers too.

The same toast money in Peloton on its first trading day in 2019: $2.47 today.

The verdict: "You'd have been better off enjoying that Avocado Toast!"

[Stephen Castellano @jscastellano]

What would a purchase be worth if you'd invested the money instead?

I built a free TradingView indicator that answers it on any stock or ETF, adjusted for inflation.

A $16 avocado toast, put into QQQ 10 years ago: $74.74 today. 🧵

$NVDA Nasdaq 100 looks oversold by an estimated 49 points. Should be at about $23,626, in my opinion, and higher assuming you figure in any potential revenue from China, along with the gross margin expansion.

Acquisitions based on half the multiple of a peer are completely sensible when the peer is a multi-billion market cap company with positive cash flow and the acquisition has a few million in revenue and negative free cash flow projected for years.
