FRO indicated dividend yield is incorrect. Actually, it has been for a long time. I thought I wrote this up, but I can't find a post from me in the forum. 1.03*4/37.01=11.1% vs Koyfin 4.75% INSW is also wrong. One must be careful with INSW. It has a long standing regular dividend and also issues larger supplemental dividends. Regular Dividend Indicated Yield .12*4/85.14=.56% vs Koyfin 5.16% Supplemental Dividend Indicated Yield 2.03*4/85.14=9.53% vs Koyfin 5.16% Combined Dividend Indicated Yield 2.15*4/85.14=10.1% vs Koyfin 5.16% None of the numbers are close. Let's look at a couple other tickers just to see if there is something widely incorrent in Koyfin. CVX as an example is close. The difference is probably explained by a variation in the price used in the denominator, last price vs closing price 1D ago perhaps. 1.71*4/190.63=3.59 vs Koyfin 3.70 HD as an example is close. The difference is probably explained by a variation in the price used in the denominator, last price vs closing price 1D ago perhaps. 2.38*4/323.88=2.94 vs Koyfin 2.98 The conclusion one must form is that Koyfin hates oil tankers. Why do you hate oil tankers? :)
