Korean Air Lines Stock Earnings Per Share

The ability to find closely correlated positions to Korean Air could be a great tool in your tax-loss harvesting strategies, allowing investors a quick way to find a similar-enough asset to replace Korean Air when you sell it. If you don't do this, your portfolio allocation will be skewed against your target asset allocation. So, investors can't just sell and buy back Korean Air - that would be a violation of the tax code under the "wash sale" rule, and this is why you need to find a similar enough asset and use the proceeds from selling Korean Air Lines to buy it.

The correlation of Korean Air is a statistical measure of how it moves in relation to other instruments. This measure is expressed in what is known as the correlation coefficient, which ranges between -1 and +1. A perfect positive correlation (i.e., a correlation coefficient of +1) implies that as Korean Air moves, either up or down, the other security will move in the same direction. Alternatively, perfect negative correlation means that if Korean Air Lines moves in either direction, the perfectly negatively correlated security will move in the opposite direction. If the correlation is 0, the equities are not correlated; they are entirely random. A correlation greater than 0.8 is generally described as strong, whereas a correlation less than 0.5 is generally considered weak.
