AI Summary
Summary
The author is running a real-money experiment where an LLM (Julius AI) manages a $1,000 Robinhood account, disclosing all trades and P/L.
Day 4 shows a -11.41% loss ($885.87) with holdings in AMD, INOD, and RGTI; the author is curious how the AI will adjust given low buying power and market volatility.
Quality assessment: This is noise / speculative experiment – the author provides no fundamental or technical analysis, only a diary-style update without a tested thesis.

Last Wednesday I started an experiment: I put $1,000 into a fresh Robinhood account for an AI to manage.
On Day 4 Julius opted to continue holding all longs. After a very cautious day of no moves on Friday, Julius opened up a new position in RGTI - building its first stake in quantum.
Day 4, 10:42am PT: $885.87
P/L: -$114.13 / -11.41%
Positions:
* 1 share AMD
* 3 shares INOD
* 3 shares RGTI
Cash/buying power: $21.17
I'll be interested to see what Julius does next. After Friday's washout and with the market wavering today, plus not having much buying power - i wonder how it takes all of these variables into consideration. Stay tuned for more updates.
As a reminder, this experiment is done with real money, with positions disclosed on every update, losses included, no hidden trades, and all trades made by Julius AI. This is not financial advice.
