I'm not sure if that happens. not just ltc I think, almost all latcoins follow the trend of btc on the market. because we know btc has the power to move the market.
The only coin that follows bitcoin is ethereum and this time litecoin is the same as another altcoin because it has been getting a huge lost when the bitcoin comes to the bearish trend. COnsider ethereum is non security coin just like bitcoin and it makes sense to see ethereum will always have a better performance than another altcoin.
