RESUMO

With the internet birth, markets are more connected and accurately priced each day. The possibility to buy and sell assets online contributed to markets efficiency, hence now it¿s easier to spread and price new information. The efficient market theory says that assets prices must react instantly to new information, thus there should be no space for arbitrage. Nevertheless this is frequently not true in the real world. In contrast with what the efficient market theory establishes, there are several factors that contribute to market inefficiency and asymmetry. A source of market inefficiency, for instance, is the transactional cost, which many times turn arbitrages practice impossible. Another example that contributes to market asymmetry is the possibility to leverage much more in the future markets than in the spot markets, since just a small fraction of the traded amount is required. These issues putted together create an effect known in the academy as the Lead-lag effect. More precisely, there is an asset that anticipates (lead) the movement of another asset (lag), in other words, we can say that one asset reacts faster to new information than the other one.
