Episode notes
No Broad Dot‑Com Bubble Yet
- Alan Pullen sees evidence for both a bubble and for justified valuations, so the picture is mixed.
- He concludes there is not sufficient evidence of a broad dot-com style bubble today, only pockets of speculative excess.
Speculation Concentrated In Startups And Data Centers
- Alan highlights speculative excess in AI startups and data-center-related names where FOMO dominates.
- He warns these areas trade on hope rather than durable fundamentals and moats.
Combine Top‑Down And Bottom‑Up Analysis
- Run both top-down and bottom-up analysis to judge market froth and individual stock valuation.
- Be selective: good investments still exist in tech and AI, but you must choose companies with real fundamentals.
