Hi,

I needed to use \boldsymbol recently, and studied the different 
solutions that have been posted on the mailing list. Using a \hbox 
wrapper seems to be the easiest way, but none of the definitions using 
\hbox took care of spacing around the symbols. Since ConTeXt now has 
equivalents of amsmath's \binrel@ and \binrel@@ commands, here is an 
improved definition of \boldsymbol.

\definetypeface [boldmath] [mm] [boldmath] [latin-modern] [modern]
                 [encoding=texnansi]

\unprotect
\def\boldsymbol#1%
   {\preparebinrel{#1}%
    \currentbinrel
    {\mathchoice
     {\hbox{\switchtoformulabodyfont             [boldmath]$\m@th#1$}}
     {\hbox{\switchtoformulabodyfont             [boldmath]$\m@th#1$}}
     {\hbox{\switchtoformulabodyfont      [boldmath,script]$\m@th#1$}}
     {\hbox{\switchtoformulabodyfont[boldmath,scriptscript]$\m@th#1$}}}}

\protect

\starttext
$a \times b$ $a \boldsymbol{\times} b$
\stoptext

This is equivalent to \boldsymbol of amsbsy.sty. I have added this to 
the wiki,

Aditya
