Need your opinion on some of the value picks I have in my portfolio

Hi Every one I’ve been practicing value investing for several years now and learning on the way . My portfolio is a mix of high-conviction Mega Caps and smaller "deep value" or speculative plays. As we head into 2026, I’m looking to tighten things up and would love some feedback on what to hold vs. what to ditch. My High Conviction Holds (The "Core"): • META / AMZN: Still see these as undervalued relative to their FCF generation. • GOOGL: Fairly valued but high conviction due to the TPU v6 rollout and AI infrastructure dominance. • NOV: Expecting a strong run through 2026 as offshore energy capex stays high. The "Undecided" List (Seeking Feedback): 1. MU (Micron) – Up 111% (Avg Cost: $162) I’m sitting on a double here. I know the HBM (High Bandwidth Memory) supply is basically sold out for 2026, but I’m wondering if the "memory cycle" is nearing a peak. Is it time to take principal off the table, or does the AI supercycle give this more room to run toward $400? 2. CROX (Crocs) – 7% of Portfolio (Avg Cost: $85.80) Currently near break-even. It’s trading at a very low multiple (\~7x EV/EBITDA), and they are aggressive with buybacks. However, the HEYDUDE recovery has been slow. Is this a "value trap" or just a misunderstood brand? 3. CRMD (CorMedix) – 3.7% of Portfolio Almost at break-even. They have a massive moat with DefenCath (FDA-approved antimicrobial lock), but they are essentially a one-product company. Does the high moat justify the concentration risk? 4. BDTX (Black Diamond Therapeutics) – 2.5% of Portfolio This was a speculative bet on their lung cancer pipeline. With FDA feedback expected in H1 2026, I’m debating if I should hold through the clinical data or exit while I’m stable. 5. The Shipping Basket (Hafnia, EuroSeas, StealthGas, GSL) – \~10% Total I’m still learning this sector. I like the cash flow, but with the EU-ETS carbon costs hitting full force this year and the Red Sea "premium" potentially fading, I feel overexposed. Should I consolidate these into one "best of breed" (like Hafnia) and exit the others? 6. Comcast - with price to feee cash flow of 5 , I couldn’t resist jumping in with a 2.5% The Strategy: I’m trying to find value regardless of market cap, but I’m worried my portfolio is becoming "diworsified" with too many small positions in sectors I’m still mastering (like Shipping).
