Best ResponseYou've already chosen the best response.0@whpalmer4 So sorry to bother you but do you think you could help me with this one too? You were extremely helpful in the other question and I actually understood it

Best ResponseYou've already chosen the best response.1okay, what is your basis (cost) for the Ferber stock if you bought 87 shares at the Day 1 high?

Best ResponseYou've already chosen the best response.1there's a shortcut you can take in this problem, by the way, but I'll wait until we've done the whole thing the "long" way to tell you

Best ResponseYou've already chosen the best response.0Or do I multiply 24.76 by 87 ?

Best ResponseYou've already chosen the best response.1okay, that's the basis for 1 share, but you bought 87 of them, right?

Best ResponseYou've already chosen the best response.1you've stumbled across the shortcut: if we buy and sell the same quantity of shares, all we have to is figure out the percentage change of the share price. this does NOT work if we don't have the same number of shares bought and sold...

Best ResponseYou've already chosen the best response.1Right. And if she sells at the high price on Day 5, how much does she receive?

Best ResponseYou've already chosen the best response.0I'm not sure how to do that math, do I divide it or multiply and then subtract or something else?

Best ResponseYou've already chosen the best response.1what is the high price on day 5?

Best ResponseYou've already chosen the best response.1so, if she sells 87 shares at 26.05, how much does she receive?

Best ResponseYou've already chosen the best response.0She would receive $2,266.35

Best ResponseYou've already chosen the best response.1Okay. How much of a percentage increase is $2266.35 over 2154.12?

Best ResponseYou've already chosen the best response.0I know the monetary difference is $115.23 but I'm not sure how to see the percentage increase

Best ResponseYou've already chosen the best response.1okay, to find the percentage change between \(a\) and \(b\), \[\text{% change} = \frac{ba}{a} * 100\%\] For example, if you go from 10 to 11: \[\frac{1110}{10}*100\% = 10\%\]

Best ResponseYou've already chosen the best response.1And to check, if you compute \(10\%\) of \(10\), that's \(1\), so increasing \(10\) by \(10\%\) gives you \(10+1 = 11\) just as we would expect from my example.

Best ResponseYou've already chosen the best response.1might be easier to remember as \[\text{% change} = \frac{finish  start}{start} * 100\%\]

Best ResponseYou've already chosen the best response.0So B is 2,266.35 and A is 2,154.12 correct? So 2,266.352,154.12 = 115.23 and that divided by 2,154.12 = 0.05349284 * 100% = 0.05349284

Best ResponseYou've already chosen the best response.1well, pretty close :) 2266.352154.12 = 115.23 115.23/2154.12 = 0.0521 multiply that by 100% and you get 5.21%

Best ResponseYou've already chosen the best response.0So the answer is 5.21%? Thank you so much once again for your patience and help!

Best ResponseYou've already chosen the best response.1sorry, 112.23, not 115.23 yes, the answer is 5.21%. Notice that we could get there more quickly by simply computing the percentage change of the share price: \[\frac{26.0524.76}{24.76}*100\% = 5.21\% \]

Best ResponseYou've already chosen the best response.1but that works only if you have the same number of shares!

Best ResponseYou've already chosen the best response.1If you had a more complicated problem, say Suzy buys 100 shares at $10, and sells 70 shares at $20, and the shares are now valued at $25, how much is the total return on her investment? there you could not use the shortcut, because some of the shares are sold at a different price, and some of them aren't sold at all. value of her investment at the end would be 70*20 + (10070)*25 = 1400+750 = 2150 return is 2150100*10 = 1150 which is \[\frac{21501000}{1000} *100\%= 11.5\%\] (and 11.5% is not the amount the price went up!)
