The datasets from which these PYPL forecasts are drawn originate from FactSet. They represent the aggregated estimates made available to academics or practitioners via the Institutional Brokers’ Estimate System (IBES). Although this seems like a fair way of predicting future profits given that they have some level expertise in investment banking, studies show there's still an optimism bias present among these professionals.

Regression-based models suffer from the use of past earnings in a linear or exponential framework. This can lead to bias because these models assume that future performance will mirror historical trends exactly, whereas business cycle dynamics and seasonality may introduce randomness over time periods.

While there is a clear consensus that a factor-based approach to investment is rewarded over time, it goes without saying that the implementation of factor investing strategies, especially in the world of long-only money-management, is rarely subject to the same consensus. Index providers who offer funds that generally contain a small number of stocks in relation to the size and risk level they are designed for, often do so by selecting certain conditions or factors within each company.

For example, some commercial indexes aim at proportionality between price movements and dividends paid out over time while others look exclusively on liquidity considerations alone; yet still more restrict their selection criteria based around corporate governance issues like transparency reports rating various aspects such as soundness levels among others relevant metrics available about any given firm when deciding whether it should be included into an investor’s portfolio.

About Transactional Liquidity

To paraphrase trader Larry Harris, transactional liquidity in the markets is the ability to trade large order sizes quickly, at low cost and time that is convenient to the trader. Many traders consider liquidity the most important characteristic of well-functioning markets.

As a general observation, low liquidity is accompanied by high volatility in price movements, and vice-versa.

Note that traders who need to perform a more comprehensive analysis can backtest the impact of liquidity on a particular security using the Tradewell platform.

How Liquidity is Calculated

This measure of liquidity displayed on the heat-maps is adapted from Amihud’s illiquidity measure, which is the ratio of absolute close to-close returns to dollar volume (Price * Volume).

This metric is calculated as a the current value ranked over the prior 50 days. A low value indicates high liquidity, while a high value indicates lower liquidity (at the transactional level). In other words, a value that is high implies a large absolute close to close return, but relatively low volume comparatively.

We measure liquidity for each component of a particular index or ETF’s in order to help understand liquidity dynamics underneath the surface.

About Liquidity Heat Map Colors

This liquidity heat map uses a color scale to display the internal liquidity dynamics of SPDR S&P 500 ETF Trust. The Y-axis is composed of each individual SPDR S&P 500 ETF Trust component, which is sorted each and every day by their liquidity rank on that day compared to the other components. This allows us to see visually whether component liquidity was high, normal, or poor. For example, if the liquidity heatmap shows more red, and darker red on a given day, it is more likely that the majority of components are highly illiquid, and vice-versa.

About Liquidity Heat Map Coordinates

The X-axis displays trading days by date, while the Y-axis contains the liquidity rank of each individual security component comprising SPDR S&P 500 ETF Trust.
