Exactly - if you examine Litecoin compared to BTC, it was lagging for quite a while - months. It made huge gains in fiat the last couple days, but relative to where it stood against BTC before, it is not as huge of a gain as it seems to be. Many coins have consistently lost ground to Bitcoin over the last year, yet appear to be a great investment, when, in reality, the admittedly less exciting standard Bitcoin would have made better gains over time. Litecoin is a rare exception, mostly because of its recent run-up against BTC.
