Yesterday I posted a comprehensive update on GME's relationship with the 420-day moving average since Keith Gill's return in May 2024. A commenter (shoutout to u /Icy-Paleontologist97) asked me to look into what the 420 MA was doing back in April-August 2020. I dug into it this morning and found some interesting data worth sharing.
This is a follow-up to yesterday's post. If you haven't read that one, the short version is: the 420-day MA has acted as a remarkably consistent support level since KG's return, the 420 daily and 69-week MAs are currently converging within $0.07 of each other at ~$24.40, and KG updated his Stocktwits to a Pro membership on 4/26/26, exactly two years after his original Stocktwits activity on 4/26/24 that preceded the whole run. Go check it out for the full context.
This post is about what happened before all of that.
The history nobody was talking about
Let's go back to November 13th, 2015. Friday the 13th.
That's the day GME closed below the 420-day moving average. It would stay below it for just under 5 years.
For most of that stretch, nobody was paying attention to the 420 MA. There was no meme stock movement, no Roaring Kitty, no Reddit army. It was just a declining stock that had broken below a moving average that happened to have a funny number attached to it.
January 18th, 2019
During that 5-year stretch below the 420 MA, there was one moment where price tried to break back above it.
January 18th, 2019.
That day, the intraday high reached $4.23, briefly poking above the 420 MA before closing back below it. The breakout attempt failed.
The 420-day moving average that day was $4.20.
The first and only intraday test of the 420 MA during that entire 5-year stretch, and the MA itself happened to be sitting at $4.20. Worth noting.
August 31st, 2020
Fast forward to August 31st, 2020. After nearly 5 years below the line, GME finally broke above the 420 MA convincingly. The 420 MA that day was $1.58.
That was the starting gun. Things got very interesting after that.
How this connects to right now
Here's the full timeline of GME and the 420 MA:
📉 11/13/15: Breaks below the 420 MA. Friday the 13th.
📈 1/18/19: Only intraday test during the 5-year drought. High of $4.23, couldn't hold. 420 MA that day: $4.20.
📈 8/31/20: Finally breaks above convincingly. 420 MA: $1.58. The run begins.
📉 8/19/22: Breaks below again. 420 MA: $37.65. Spends 21 months under it.
📈 5/13/24: KG returns. GME reclaims the 420 MA. 420 MA: $19.13. Holds above it for 295 consecutive trading days.
📉 8/1/25: Pattern breaks down. Extended period below the MA through early 2026.
📈 4/15/26: Reclaims the 420 MA again. Currently 12 trading days above it.
And as of today:
- 420-day MA: $24.46
- 69-week MA: $24.39
- Gap between them: $0.07, the closest they've been in this dataset going back to 2021
What does any of this mean?
Honestly? I have no idea. I'm a sped teacher, not a quant.
What I can say is that the 420 MA has been a significant level for GME going back to at least 2015, well before meme stocks were a thing. The $4.20 MA on the day of the only intraday test during that 5-year stretch is an interesting data point. It happened before anyone was paying attention to meme numbers.
Whether any of this matters for future price action I genuinely can't say. The 420 MA has been reclaimed before and lost again. I said that clearly yesterday and I'll repeat it today. Twelve trading days above a moving average is not a guarantee of anything.
But the historical context keeps getting more interesting the deeper I dig. Make of it what you will.
