if you ignore brokerage fees

and today you bought

3000 sgr at .07 the cost would be 210 dollars and you also bought

1000 ker at .16 the cost would be 160 dollars

at this stage by buying 1000 ker at this price you in effect aquire 3000 sgr for 160 dollars at a unit cost of .053 cents.....so today i will sell my remaining sgr at .07 take my tax loss...and with the proceeds buy ker...but if you do not believe in gibson and/or sgr survivability then one should be dumping
