For those who care about SecondMarket's BIT fund, here is a plot of
data tabulated by @jl2012:

The first four plots are taken from the tables in that thread. The red line is the share value, equal to the USD market price of 0.1 BTC, by definition.
The fifth plot ("Est. Accum. Investment", purple) was computed by me: it is the estimated net dollar amount that was invested by clients, assuming that each change from one day to the next was either all investment or (rarely) all liquidation. With this assumption, since the foundation until today, clients appear to have have invested ~68 M USD in the fund, while the value of all the bitcoins held by it is ~30 M USD. Recall that the fund has suspended redemptions (withdrawals, liquidations) since 2014-10-29.
Note the four large steps last November, corresponding to 6000-7000 BTC each. These atypical investments may be due to a single investor. I wonder if they are the cause or consequence of the small rise in price at that time.
