Quarter flow (concentrated managers)

Change in managers (55 → 55): 2 opened · 2 exited = 0

Net flow in the quarter: −$24.7M (−33 shares) · bought $23.2M and sold $47.9MShares 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.

The set of concentrated managers changed between quarters: with the set as it was then, 54 held it last quarter (the chart point); with today's set, 55 (the base for the change).

Balance sheet
Quality vs sector
40/100

Bank, insurer or other financial company: we do not show net debt / EBITDA or free cash flow. Its cash flow moves with loans and the investment portfolio, and its debt is part of the business: those figures do not read as they do for an industrial company.

Figures from the statements the company filed with the SEC (10-K, 10-Q). Free cash flow = operating cash flow − capital expenditures; empty if the company does not report capex. “Quality vs sector”: 0 to 100, the average of its percentiles in ROE, operating margin, free-cash-flow margin, revenue and earnings growth and net debt / EBITDA (at least 3 needed) against companies in its sector above $300M. How each figure is calculated

Earnings quality and debt

Operating cash flow ÷ net income (12 months)
0.54

Bank or insurer: debt ratios do not apply.

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.
