What's Your APR?

My Recent Stock Picks: Gains and Annualized Returns That Pack a Punch!

As an investor always on the lookout for promising opportunities, I recently dove into a diverse set of stocks and ETFs, from tech innovators to precious metals. With the help of Grok 3, an AI-powered tool from xAI, I’ve crunched the numbers to see how my portfolio is performing and annualized the returns to get a sense of their potential. The results? Some impressive gains in a short time! Let’s break down my holdings, their unrealized gains, and the effective Annual Percentage Rates (APRs) that show what these returns could mean if sustained over a year.

The Portfolio Snapshot

Using current market prices as of September 15, 2025, and my unrealized gains, Grok 3 estimated how long I’ve likely held each position (based on recent price data) and calculated the effective APR. Here’s the rundown:

Ticker	Full Name	Unrealized Gain (%)	Holding Period (Days)	Effective APR (%)
CRDO	Credo Technology Group Holding Ltd	+49.84	87	305.77
SLV	iShares Silver Trust	+16.36	67	109.28
SES	SES AI Corporation	+12.32	41	150.80
FUBO	fuboTV Inc.	+11.48	45	113.75
MBRX	Moleculin Biotech, Inc.	+5.42	12	254.26
SOUN	SoundHound AI, Inc.	+5.12	12	233.91
OPEN	Opendoor Technologies Inc.	+4.14	10	223.13
VNQ	Vanguard Real Estate ETF	+2.18	6	183.76

Standout Performers

Credo Technology (CRDO) takes the crown with a jaw-dropping 49.84% gain in just 87 days, translating to an annualized return of 305.77%. This tech stock’s surge reflects its strong position in high-speed connectivity solutions—a hot sector in today’s digital economy.

iShares Silver Trust (SLV) delivered a solid 16.36% gain in 67 days, annualizing to 109.28%. With silver often seen as a hedge against inflation, this ETF’s performance suggests a timely bet on precious metals.

Moleculin Biotech (MBRX) and SoundHound AI (SOUN), both held for just 12 days, posted gains of 5.42% and 5.12%, respectively, with APRs of 254.26% and 233.91%. These short-term wins highlight the potential of biotech and AI-driven companies, though their volatility calls for careful monitoring.

Even the Vanguard Real Estate ETF (VNQ), with a modest 2.18% gain in 6 days, annualizes to an impressive 183.76%, showing real estate’s steady appeal in a short window.

Why These Numbers Matter

The effective APRs give a sense of what these gains could look like if sustained over a year, though short holding periods can inflate these figures. For instance, MBRX’s 254.26% APR over 12 days doesn’t mean I expect that return annually—it’s a snapshot of momentum. Using Grok 3 to calculate these metrics helps me stay on top of my portfolio’s performance and spot trends early.

What’s Next?

These early gains are exciting, but investing is a long game. I’ll keep tracking these positions, balancing high-fliers like CRDO with steadier bets like VNQ. Grok 3’s ability to analyze price data and estimate holding periods has been a game-changer, giving me clarity without hours of manual number-crunching.
