Quarter flow (concentrated managers)

Change in managers (8 → 6): 1 opened · 3 exited = −2

Net flow in the quarter: +$24.3M (+2.4 M shares) · bought $53.4M and sold $29.1MShares concentrated managers added minus those they cut, valued at the 13F quarter-end implied price, not each trade's price. It is a different measure from the change in managers: the two can have opposite signs.

Accumulation: combined they have held more shares for 5 quarters in a row (3 added, 0 trimmed). It is the combined share count of those still holding it: one large buyer can outweigh many who trimmed.

The set of concentrated managers changed between quarters: with the set as it was then, 7 held it last quarter (the chart point); with today's set, 8 (the base for the change).

From the statements the company filed with the SEC (10-K). The change compares average diluted shares of each fiscal year, on today's basis: negative = it bought back more than it issued; positive = dilution. “No data” = the company does not report that item under a tag we can read; it does not mean zero.

From the figures the company filed with the SEC. Cash flow over net income near or above 1 means earnings are collected in cash; far below, that part is accounting. Coverage says how many times operating income pays the latest fiscal year's interest. Maturities come from the debt note of the latest annual report, counted from its closing date. “No data” never means zero.
