Is it really so?
I didn't check other coins since I'm not very interested in them (so bear with me). Nevertheless, even if it is, you shouldn't forget that Litecoin went down a lot slower than Bitcoin and I guess a lot slower than the rest of the pack.
Yes, a basic look at Coinmarketcap shows that Bitcoin and most other cryptocoins recovered more than 10 (and some more than 15%, like ETH) in the last 24 hours, while LTC got only ~5%.
It is surely related to the slower downtrend of LTC you mention. But the point is that I think LTC is used like a hedging vehicle for the case that Segwit2x fails so Litecoin could continue with the privilege to be the "biggest coin with SegWit". If this money goes out of LTC I think it will fall drastically - unless they really manage to get real-world adoption of Lightning, or at least atomic swaps, faster than BTC
I certainly see your point
As well as where you likely fail in your reasoning. In short, you implicitly assume that Litecoin growth was specifically due to SegWit (and Lightning Network) activation, but, as to me, this is a false assumption (at least, for the most part). If it were so, we would see the Litecoin price spike even before SegWit activation or soon thereafter. But it didn't happen, and, in fact, it couldn't since SegWit (and still more Lightning Network) are pretty irrelevant and inconsequential for this coin as of yet. In my view, Litecoin rose to prominence, so to speak, not because of SegWit as such but rather because of its robust improvement model, i.e. the way the required changes get accepted without much ado, without needless and useless showdown. And it seems that Litecoin has been quickly rising these last hours
