Friendly reminder that $MRK is well positioned and well incentivized to purchase $LQDA. Yutrepia fits very well with Merck's respiratory portfolio. https://t.co/JAdLguTw7D

@GullCoveCapital Like all other opposition pieces, this article assumes "facts" not in evidence. The reality is joint testing is needed. $NN has been pushing for this for 2 years, but the opposition has resisted. Why is that? IMHO the key part of the article is below: https://t.co/LFpFs7ebCu

Like $GLW, I wish margins/ROIC were higher and capital intensity were lower at $AMKR. Yet, with the stock now back around $46 (largely flat YTD and cut in half from its highs), the Amkor setup now seems pretty good over the next 3-4 years due to their scale, new capacity investments, and the increasing importance of advanced packaging capabilities.

Despite my past skepticism, $GLW around its current $125 per share ($110 b cap) actually seems fairly compelling given the company’s scale, leading market position, and multi-year growth ramp.

@SowingAlphaSeed Of the US indexes, my personal holdings are now most correlated to $dia. Weird world.
