Hi Lukas,

Best advise for the moment: use \eqalign and \eqalignno from plain.tex. 

There is a math module in the works but its development has lagged behind
the updates of context itself, so much so that it is currently completely 
broken.

Thank you Taco.
But I'm not skilled in plaintex (I tried your suggestion - unsuccesfuly).
Could you please give me a more descriptive advise how to adjust the
following part of text in ConTeXt to be broken into more lines?:

- -------------
\placeformula
\startformula
        \sigma_P^2 = X_1^2 E\left[\left(R_1j - \bar{R}_1\right)^2\right] +
2X_1 X_2 E\left[\left(R_{1j} - \bar{R}_1\right)\left(R_{2j} -
\bar{R}_2\right)\right] + X_2^2 E\left[\left(R_{2j} -
\bar{R}_2\right)^2\right] = X_1^2 \sigma_1^2 + 2X_1 X_2
E\left[\left(R_{1j} - \bar{R}_1\right)\left(R_{2j} -
\bar{R}_2\right)\right] + X_2^2 \sigma_2^2
\stopformula
- ------------

Thank you.

Lukas

How about this?

$$\eqalign{
 \sigma_P^2 &= X_1^2 E\left[\left(R_1j - \bar{R}_1\right)^2\right] +
2X_1 X_2 E\left[\left(R_{1j} - \bar{R}_1\right)\left(R_{2j} -
\bar{R}_2\right)\right]\cr &\qquad + X_2^2 E\left[\left(R_{2j} -
\bar{R}_2\right)^2\right]\cr &= X_1^2 \sigma_1^2 + 2X_1 X_2
E\left[\left(R_{1j} - \bar{R}_1\right)\left(R_{2j} -
\bar{R}_2\right)\right] + X_2^2 \sigma_2^2\cr
}$$
