$COST - Lol. Dopest thing you'll read A while back, I remember wanting to get into algorithmic trading. I love math & all, but once one thing led to another & eventually I found myself trying to understand mechanics & quantum physics & computer learning - there was no way lmao. I tried, & it ultimately did help come up with my own strategy that I've gotten accustomed to. But since then, the most helpful & my favorite recollection of all things math & stocks is the bubble report. Chances are if you've seen bitcoin - you could tell it was a bubble, but probably didn't know when it'd pop, how long it'd take to recover (if ever), & where the top of it would be. Whether it's stocks, forex, bitcoin, commodities, etc., a bubble is a bubble. The best way (might be the only.?) to describe a 'bubble' is when exponential growth exceeds linear growth; historical growth (x) surpasses the equilibrium rate of growth (y) over time, & instead of a linear graph - you need a logarithmic graph just to make fit. A new bubble report is released each month & I remember seeing Costco on it w/ a 98% "bubble" score. Kept it on watch, but seeing as implied volatility is in it's top 25 percentile - better late than never lmao. I made this layout back during my experimenting on producing actual results to use moving averages as a "bubble" finder - bitcoin was my original start & I saved it since then. Although you can only see one (red) moving average, there's two. The 2nd is a weighted moving average for a half a year longer, while the red is a shorter, exponential moving average based off lows. I made the 2nd the same color as the background w/ thicker width that way whenever the (red) crosses over it - both moving averages disappear in an indication of faster exponential growth without an equilibrium. Although you can't see the 2nd moving average - click on any one of the yellow rectangles & you'll get an idea. I was supposed to make a comment about how this chart reminds me of Venezuela's inflation rate but, yeah. Better late than never. If you wana check out that bubble report,
