Testopedia explains Holder
Buyer, owner, holder and long are all synonymous. The buyer of a security is considered bullish because he wants the price of the security to rise. He also has limited risk, as the most he can lose is the amount of money he invested, but, in the case of equities, has unlimited upside potential; there is no limit to how high the price of a security can go.
