2 yen, but if the 4 months were February to June and if you've already
closed the account then you might not get the 2 yen.

A different stock each day.  Each morning you can read the day's newspaper
to see which stock you should have bought 2 days ago and sold 1 day ago.
Sometimes it might even tell you which stock you should have bought and sold
the same day 1 day ago, but you won't really know for sure until one more
day.  And of course sometimes the order of buying and selling should be the
opposite (shorting).
