I believe LTC is pumped by hardware manufacturers like bitmantech to sell their latest high end scrypt mining hardware to make it look like worth buy for mining and it will crash badly as soon as they ship their batch and miners starts dumping for profit.
That is a good possibility but what i understand is that because they have reached a deal that all the major minors are ready to accept segwit we saw the price started increasing and they might be using this price range as a leverage to sell their hardware.
