BofA said about 70% of its bear-market indicators were triggered and the S&P 500 looked overvalued, while Serenity noted the bank's earlier Korea chip bubble warning was followed by record highs.
Bank of America warned in a June 5 report led by Savita Subramanian that risks of a stock market top are increasing, saying roughly 70% of its bear-market indicators had been triggered and that the S&P 500 was statistically overvalued on 17 of 20 metrics. The bank also pointed to widening performance gaps and rising capital expenditure among mega-cap cloud firms as signs of speculation and market divergence. On June 9, Serenity challenged investors treating BofA's bearish view as definitive, citing the bank's March warning that EWY/KOSPI-linked Korean memory chip stocks tied to SK Hynix and Samsung were in an extreme bubble, after which those shares went on to reach record highs.
