Stewart, Tim,<br />

Ho, I forgot this graph (run length in # of days, where # 0)<br />

RunLength.pdf: stats on the length of a "run" of contiguous business days spent in the<br />

threshold list<br />

3) Analyse of a possible price effect<br />

(requires matching CRSP data)<br />

Transitions.pdf: Beta Excess Return (source=CRSP) cond. on transition in/out of the list<br />

Seq.pdf: Beta Excess Return after a big increase in fails for a threshold security,<br />

from day 0 (day of the increase) to day 16 after the increase, for 5 definitions<br />

of "big". Sequences are clean (no overlaps). It does not show clear<br />

evidence of squeeze (however, there is a weak positive price impact on day 11/12).<br />

I did the same computation for trade volume and turnover, but did not find any effect.<br />

I am taking a day off today, and will be back on Monday. I am looking forward to discuss<br />

all these with you.<br />
